Abstract
Recording a replay-able trace of execution of an executable entity using cache data includes executing one or more threads of the executable entity concurrently across one or more processing units of the one or more processors. During execution of the one or more threads, a separate replay-able trace is recorded for each thread independently. Recording includes, for each thread, recording initial processor register state for the thread. Recording also includes, for each thread, and upon detecting a processor data cache miss, recording at least one line of cache data imported into the processor data cache.
